Re: error LNK2019: unresolved external symbol

Posted 29 June 2011 - 03:50 AM

The linker error: "unresolved external symbol" means that the compiler can not find the function or variable in any of the files in the project. So to fix the error you will need to insure that the implementation file that contains the function in question is indeed part of the project. Check the spelling, insure that the parameters are identical, insure that the return value is identical, this includes any const qualifiers if required.
